(1) WING FLAP AND LANDING GEAR CON- TROLS. - The wing flap motor is controlled by a toggle switch. The time required to lower the flaps at 147 mph is between 15 and 30 seconds. WARNING In returning the flap control switches from “DOWN” to “OFF,” be sure the toggle switch is not allowed to snap to “UP,” resulting in immediate retraction of the flaps. (2) The main landing wheels and tail wheel are operated simultaneously by a toggle switch. A hinged guard prevents accidental moving of the switch to the “UP” position. Warning that the landing gear is not fully extended is given by a green indicator lamp fail- ing to light, and by a horn which sounds if any throttle is closed. (3) COWL FLAP VALVES. - Cowl flaps are op- erated by four valves, each valve controlling the flaps on one nacelle. The valve must be turned to ‘ ‘LOCKED’ when the desired position of the flaps is reached. Slight “cracking” of the control valve will result in relatively slow travel of the flaps when close adjust- ment is desired. (4) FUEL BOOST CONTROLS. - The fuel boost pumps, operated by four toggle switches, provide fuel 16 KEY TO FIGURE | 8. TURRO AND MIXTURE IGNITION SWITCHES . FUEL BOOST PUMP CONTROL LOCK SWITCHES 9.
